Mechanical Engineering

Hydrix continuously aims for excellence in mechanical engineering to create products that meet our Client’s requirements, are robust and reliable, and can be economically manufactured. As a team, we achieve this by generating innovative solutions, reviewing each design iteration back to the requirements and adopting a rigorous process of design for manufacture. Hydrix engineers are acutely aware that every additional component in the product is a cost to, and reduces the margin for, our Clients.



Hydrix engineers have experience designing motors, and mechanisms on a variety of products - from 100’ diameter satellite dishes with servo controlled drives to multiple stepper motor driven robotic axes on diagnostic instruments and miniature stepper motor and dc motor driven mechanisms in hand-held devices.


Team members have experience in heating and cooling devices both for active temperature control in medical devices and removing waste heat from electronic assemblies housed within drip-proof enclosures, - e.g. Hand-held diagnostic instrumentation.


We frequently work in close co-operation with industrial design houses, where they develop the ergonomics, human factors, styling and graphics for the GUI, and Hydrix develop the internal mechanisms, electronics and software. Hydrix and the industrial designer communicate closely to ensure a smooth interface between the PCB and buttons or connectors on the case.


Hydrix engineers have designed products where the electronics and active mechanisms are directly mounted in injection moulded housings, and on lower-volume products where all parts are mounted on a sheet metal or cast chassis. A chassis can be a viable solution where there are multiple PCBs, and these can be pre-assembled to the chassis and connected and tested by the PCB manufacturer prior to shipment for final assembly.


The Hydrix team has considerable experience in successfully applying Boothroyd-Dewhust Design for Manufacture techniques to improve manufacturing cost of products while maintaining function and reliability.  Examples of this are evident on their single-use medical disposables, vital signs instruments connected to a patient in intensive care and automation instruments used in hospital laboratories. They have designed low volume products and prepared full assembly instructions – e.g. Laboratory Instruments, as well as designed for full automated assembly – e.g. asthma inhalers.


Hydrix engineers have experience in designing pneumatics and hydraulic systems – both combining off-the-shelf components and designing custom hydraulic and pneumatic assemblies, such as a variable flow hydraulic pump and high speed (30Hz) hydraulic actuator for opening valves on a marine engine.
